4.7% divide amount of weight lost by the original weight.
Engineering answer:


Formula: loss/base weight*100


so 13/276*100 or 4.71%.








Marketing answer:


Engineering provided formula:loss/base weight*100


known wt loss: 13 lbs in 2 weeks


projected wt loss: 28.16 lbs / month


(remember there are 52 weeks in a year, but only 12 months)


round off to 29


so weight at end of 1 month = 276-29 or 247


use projected weight as base weight


so weight loss = 29/247*100 = 11.74% per month !!








Legal answer:


individual results vary
weight lost





Divided by





original weight





So for you it would be 13/276= 4.7%
